When the wiper/washer switch is in the high speed setting, the windshield wiper motor also receives a ground signal directly from the SCCM, bypassing the logic within the windshield wiper motor module. This fail-safe circuit makes sure the windshield wipers function in high speed mode in the event of a LIN communication failure.
Mist Wipe
When the mist wipe function is activated, the SCCM sends the request to the windshield wiper motor over the LIN to perform a single wipe of the windshield. The windshield wipers operate for as long as the mist wipe function is active.
Windshield Washer
When the windshield washer switch is activated, the SCCM sends the washer request to the windshield wiper motor over the LIN. The windshield wash relay is internal to the windshield wiper motor. When the windshield wiper motor activates the windshield wash relay, voltage is provided to the washer pump, directing washer solvent to the windshield. When the switch is released, the windshield wiper motor continues to activate for 3 additional wipes and then turn off.
Courtesy Wipe
When the windshield washer is requested, a few seconds after the windshield wash cycle has completed, an additional wipe of the windshield occurs to clear any washer solvent remaining on the windshield.
The courtesy wipe feature can be configured on/off using the message center.
Intermittent Wipers
When the wiper/washer switch is in an intermittent setting, the windshield wiper motor activates at timed intervals. The lower the setting, the longer the interval between wipes.
Speed Dependent Wipers
When the wiper/washer switch is in an intermittent setting, the speed dependent feature increases the frequency of wiping as the vehicle speed increases to compensate for the extra moisture that accumulates on the windshield.
The SCCM receives the vehicle speed from the PCM. The SCCM then sends the vehicle speed data to the windshield wiper motor through the LIN.
Rain Sensitive Wipers (if equipped)
When equipped, the rain sensitive wiper feature replaces the intermittent wiper feature. The rain sensitive feature is active when the wiper/washer switch is in any of the 6 auto/intermittent sensitivity settings. The setting closest to OFF is the least sensitive to moisture, the highest setting being the most sensitive to moisture.
The rain sensor sends data through the LIN to the windshield wiper motor. Based on the data received from the rain sensor and the auto/intermittent setting from the wiper/washer switch, the system automatically activates and adjusts the wiper speed and frequency when moisture is detected on the windshield.
If a fault is detected with the rain sensitive feature, the windshield wipers change to a default intermittent mode. The timing of the wipers correspond to a standard intermittent setting based on the auto/intermittent sensitivity setting on the wiper/washer switch.
Wiper Activated Exterior Lamps
When the headlamp switch is set to AUTO, the BCM turns the exterior lamps on within 10 seconds of the windshield wipers being activated by the wiper/washer switch. Approximately 60 seconds after the windshield wipers turn off, the BCM turns the exterior lamps off.
If the rain sensitive wipers are activated by moisture detected on the windshield when the headlamp switch is in the AUTO position, the BCM turns the exterior lamps on after a time delay. Shortly after the rain sensitive wipers
